Mix equal parts of solutions A and B. You will not need much. I found about 5ml of each to be just enough for a full page. Spread the solution evenly over a sheet of paper. Those spongy paint brushes work well. I used regular printer paper but this process should work on just about anything, including fabric. Remember the solution is sensitive to UV light. It is best to do this in a dimly lit room, or at least a room with no natural sunlight.
Put the paper somewhere dark and let it dry. Wait for a couple hours. If the paper is not completely dry when you do the exposure, the image will come out fuzzy.
